Does anyone have any suggestions on how to make a latte with these? Any idea what measurements I should use?

Well here is how I make my chai;

Bring to a boil 2 cups of milk and 1 cup of water, or whatever ratio you prefer. You can make a bouquet garni with the spices, or I usually just mix them right in there. I let it simmer with a lid on it for 10-15 minutes, and strain it out when its done. I sweeten it with brown sugar and vanilla extract.

The way I make my Chai latte is: Brew tea the normal way. I put some milk in a cup that can be microwaved, but double the amount of milk I would use in a cup of tea. Microwave for about 45 seconds then froth it up using a hand held blender stick or a metal wire frother(they use them for mixed drinks I think) and then add my brewed tea (with or without sugar) to the milk mixture. Yummy!
